Benefits of technology

Enables dynamic and distortion-corrected image projection onto various surfaces within a room environment, allowing for flexible and efficient display management without the need for precise geometry or projector parameters, enhancing usability and freedom in image placement.

Problems solved by technology

However, as can be understood, since the projector is stationary, some surfaces would be tilted with respect to the projector, thereby leading to a distortion in the projected image.

Embodiment Construction

[0018]FIG. 1 depicts a generic room 100, e.g., office, classroom, conference room, etc., where ePaper surfaces (eSurfaces) may be attached anywhere on walls, e.g., 110, 120, 130, or even on desks as personal information sheets during meetings, e.g., 140. Within the context of this disclosure, eSurface refers to any sheet-like surface having the property of accepting optically projected image when powered, and retaining the projected image after the power is turned off. These eSurfaces may be moved easily because ePaper can be lightweight. Additionally, because the eSurfaces only require power when the content is changed, they can be used not only to replace conventional electronic screens, but also as displays with relatively static content like signs, logos, and artwork. Particularly for shared spaces, like classrooms and conference rooms, the ability to quickly and easily change the content of the displays in the room has significant appeal. One can imagine corporate conference ro...

Abstract

A system for providing a dynamic audio-visual environment using an eSurface situated in a room environment; a projector situated for projecting images onto the eSurface; a camera situated to picture the room environment; a central processor coupled to the eSurface, the projector and the camera. The processor receives pictures from the camera for detecting the location of the eSurface; and controls the projector to aim its projection beam onto the eSurface. The eSurface is a sheet-like surface having the property of accepting optically projected image when powered, and retaining the projected image after the power is turned off.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The subject invention relates to operation of environments containing photo-addressable ePaper technology.[0003]2. Related Art[0004]Photo addressable ePaper has been developed by the subject assignee, Fuji-Xerox of Japan. The photo-addressable ePaper technology provides a photosensitive medium that, when energized, accepts a light input to generate an image that is maintained on display after the power is removed from the media. For example, if the media is energized and one uses a laser pointer to write on the ePaper, the writing will remain displayed on the ePaper after the power is removed. Similarly, if one projects an image onto the ePaper using, e.g., an LCD projector, when the ePaper is powered, the projected image will remain displayed by the ePaper after the power is removed. There are two different types of ePaper, one that is written to by light from behind, and one that is written to from the front. For further information r...
